In 1900 New Zealand was given a choice to join Australia as a state and one of the commonly cited reasons against joining was that NZers were worried that Australians were so racist that they would cause another war with the indigenous Maori people.

Not that NZers at the time were treating Maori people with fairness and dignity, but Maori could at least vote and Australia was actively genociding the Tasmanian aboriginal people at the time so…

Not exactly as bad as all other anglo countries.
